After a few months of experimentation, we found no 3rd party (i.e., non-Apple branded) HDMI <> VGA adaptors which worked well and some which didn't work at all on our Macs. We bit the financial bullet and purchased Apple-branded adaptors and they work perfectly. We found the same with Thunderbolt & USB <> gig-Ethernet adaptors and Lightning <> ...

There seems to be a problem with the radeon driver when booting. You can test a fix by doing this: When you see the grub menu, press 'e', which will allow you to edit the entry. Go to the line with "linux...." and look for where it says 'ro'. After the 'ro', add 'nomodeset' (without quotes), and then boot (press F10). If that works, you can make it ...

Being that VGA is an analog signal, and (Mini) DP / HDMI are both digital signals, an adapter will be required. Given that you wanted a solution that used HDMI, a powered HDMI port is necessary, which is not be included with the MBP, in addition Apple does not support such a configuration: Can the HDMI port drive analog displays (VGA displays, for ...

The MacBook Pro's HDMI port has a DVI-D implementation. This means it has no analog signal, which is what VGA relies on to connect. More information here: apple support forums . Apple supplies an HDMI to DVI adapter, which could solve your problem if your monitor has a DVI port. If not, then I would suggest getting a Thunderbolt (Mini DisplayPort) to VGA ...

Open System Preferences → Display. Hold ⌥option which will change the ‘Gather Windows’ button to ‘Detect Displays’. Clicking it might detect your VGA.

The recommended way is to use the Thunderbolt (Mini DisplayPort) to VGA converter. http://store.apple.com/us/product/MB572Z/B/mini-displayport-to-vga-adapter?mco=MTA4NDU0NjA The Apple HDMI does not supply signal to VGA monitors. The Cable you have is good, but only for Digital monitors and VGA is Analog type. OK if you are sufficiently confused now, just ...

It is possible to connect a VGA and a DVI display to one USB-C port on the MacBook, but you need two USB-C adapters in a daisy-chain fashion and a HDMI-DVI adapter. First you connect the USB-C Digital AV Multiport Adapter (part number MJ1K2AM) to the MacBook USB-C port, then you connect the USB-C VGA Multiport Adapter (part number MJ1L2AM) to the USB-C port ...

On my 2014 MacBook Pro with 2 Thunderbolt ports I found HDMI port to HDMI-VGA adapter did not work, but if I used my Thunderbolt to HDMI adapter then plugged the HDMI to VGA adapter into that, the VGA signal to the external monitor worked fine. Neither adapter are Apple branded, just generic. I also had to turn off Dynamic Switching of the graphics cards (I ...

The Apple 15" MacBook Pro specification about Graphics and Video Support says: Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors Thunderbolt digital video output Native Mini DisplayPort output DVI output ...

Apple miniDisplayPort to VGA adapter


3

Certainly. The Retina MacBook Pro has one HDMI output and two Thunderbolt ports, so you can run the internal display and three external monitors as long as you can accept HDMI on your third monitor (with or without an adapter/converter). Any mini-DisplayPort adapter from Apple will work from Thunderbolt in addition to adapters labeled as Thunderbolt.

With that adapter, you can only use 1 video output at a time. From the product description in the link you provided: Alternative Video Outputs: Connect a display to your computer using either the HDMI port (4K@30Hz Max resolution) or VGA port (1080p Max resolution). If both are connected, only HDMI will output Emphasis mine To connect two monitors, ...

I use a product from http://xlr8.com/ to give me a video input on my mac, then use a VGA-to-TV adapter to stream powerpoint over ustream. Video is really choppy and crappy looking, but for simple non-moving slides, it's OK for ustream.

The supported resolutions defined on the Apple pages are for the built-in screen which is, pardon the pun, comparing apples to oranges in this case. Plugging an external monitor in will show those resolutions that the monitor supports and you will be able to achieve the maximum resolution of the Dell monitor which is 1600x900

You can get DVI to HDMI adapters from around $4 online on Amazon, (just search for ‘DVI to HDMI’ on any online shopping site). As for the quality, most of the adapters that I have seen are able to do HD video and such. Hope this helped!

I have a late 2011 15 inch MBP and have successfully used Thunderbolt adaptors to connect to monitors via DVI and TV via HDMI with excellent results. You don't need a 16:10 screen - the display will adapt to various screen dimensions. I think you can plug just about anything in with a very high chance of success.

Seeing that this question has become popular, I will tell you how I resolved the issue... I was using a fake adaptor, but it worked with Mac OS X flawlessly for two years. Strangely, it only works now when booting with other systems (like xubuntu live cd). What I did to solve it was buying an original adapter from Apple.. I hope it will last until my ...

I don't know which product you have, but I own an Insignia HDMI to VGA adapter. There's a micro-USB port on the adapter which I need to plug into a power source, and it then works. I just plug it into my computer for the power and have a USB hub on the other side for my USB needs.

You'd just be better off buying another monitor, as that is Mini-DVI out not in. I'm sure that there are ways around this, but buying a separate monitor would be way easier.

Once in GRUB press the e key. We’re now going to disable the AMD graphics card while we boot into the Ubuntu Live CD. Look for the line set gfxpayload=keep. Once you’ve found it, type the following lines underneath to disable the AMD graphics card: outb 0x728 1 outb 0x710 2 outb 0x740 2 outb 0x750 0 Next find the kernel line and after “quiet splash” , add ...

I highly recommend a thunderbolt dock to do this. In my experience it isn't possible to daisy chain the adapters as described in one of the other answers. In fact, the port they are using to daisy chain is only for power in anyway. Yes the connector fits, but doesn’t function. USB-C docks that offer multiple monitors usually rely on DisplayPort Multi-Stream ...

That looks like a white MacBook Core Duo 13-inch, and while I have not seen one of those for a while (congrats on keeping it running!) I believe that is what is called a mini-DVI port. So a search for mini-DVI to VGA should find you the adapter you are looking for. I doulbt Apple still carries it and you might have to buy a used adapter (ebay and the like) ...

Adapters can be finicky things. I have had mixed results even with genuine Apple display adapters. You would think something this simple would be a no-brainier; just buy, plug in and go to work. It may be the adapter itself that is giving you problems so you will want to return it and get another. However, as has been previously stated, you should be ...

To correct the resolution, open the Display panel in System Preferences, connect your monitor if not already connected, and look for the Display preference window on the projector. Click on "Scaled" instead of "Best for display". Then hold the Option (⌥) key while clicking again on "Scaled" and you will see a list of resolutions to choose from. You can ...

The problem that you are facing is simple to fix. Actually there is no inbuilt Thunderbolt to VGA drive inside a MacBook/Mac mini. So what you should do is install a Mini DisplayPort to VGA Firmware Update v1.0. After installation restart the system, then connect your thunderbolt to VGA connector. It will work perfectly fine. Here is the link for the driver ...

You can use a USB Display Adapter. One like this could work. Some display adapters only support digital formats (HDMI, DVI-D...) so if your projector only supports analog signals (i.e. VGA) then make sure the adapter you get supports it. One limitation of USB display adapters is their limited bandwidth, and therefore limited resolution. For a ...

Both MacBook Pro and the Mac Mini have Mini-DisplayPort on them. You can connect the Mini-DisplayPort to an Minii-DisplayPort-to-VGA converter and then, connect VGA cable on it to a two-port VGA DDM KVM switch, such as ConnectPRO's UR-12+. I had been using this configuration for years without problem.

Well, the Mac mini should include both an HDMI connector, as well as a Thunderbolt connector. If you are actually using VGA monitors with VGA connectors, you would simply need one HDMI -> VGA adaptor for one monitor, and one Thunderbolt -> VGA adaptor for the other. If your monitors are newer, you might like out and one will already have an HDMI ...
